What Are The Best Tips For Commercial HVAC Installation?

Commercial HVAC units are used around the world in malls and commercial buildings to offer a perfect shopping experience especially when it is blistering hot outside. These units tend to be expensive but more important is their installation. Even a professional with years of experience can sometimes get it wrong. Therefore, we have compiled a list of some important tips to keep in mind when it comes to installing a commercial HVAC which shows why it’s impossible to install it without commercial AC repair services.

Determining Load Capacity

The first and most important thing you need to consider is the load capacity. Although, this is the most basic factor, surprisingly many people still get it wrong. Commercial HVAC units come in a variety of shapes and sizes suited for different purposes.

You cannot expect an HVAC unit installed in a retail store to cool down an entire mall. This is why HVAC units installed in hospitals and other relatively bigger buildings tend to be heavy-duty and are specifically designed to work round the clock to maintain the temperature.

To determine the right load capacity, you will need to consult a professional and figure out the building size or area. Additionally, you will also have to consider the direction of the sun and other external and internal factors.

Choosing The Right Commercial HVAC System

From the outside, HVAC units look more or less the same. However, as mentioned earlier, each HVAC system is designed to serve a different purpose. That said you would have to choose between a single split, a multi-split, a variable refrigerant volume, a variable refrigerant flow system, or the traditional ductwork air conditioning system.

Then again, picking the right option is going to be difficult especially if you are not aware of the basics. Seek the help of a professional and convey your cooling and heating needs. The consultation may cost you but will be worth every penny in the end.

Making Space For The Condenser

Whatever type of HVAC unit you decide to install, you will need to make space for the condenser. Depending on the space available, you might want to place it on your roof, in the attic, or anywhere else but not in harm’s way. Keep in mind that the condenser is a major component of the HVAC unit.

Without it, the system will simply fail to perform. This means you need to be careful while choosing a place to install. External factors such as extreme weather conditions can take an extreme toll on these components.

Direct exposure to sunlight, thunderstorms, etc. can incur damage. Therefore, think twice before choosing a place to position the condenser.

Assessing The Current Ductwork

Part of installing a new HVAC system includes assessing the current ductwork. If you are upgrading your HVAC system, the contractor will need to take a look at the condition of the existing ductwork. If it has been more than a decade, chances are that the ductwork will need to be upgraded as well.

Old ductwork is prone to leakages that reduce the efficiency and effectiveness of the air conditioning system. As a result, your energy bills are prone to increasing every month. However, if you have maintained your ductwork all these years, you might not need an extensive ductwork service.

Moreover, depending on the location and installation of the HVAC system, you may also require custom ductwork.

Consider The Budget

The next important factor you need to consider is the budget. Even if you are able to afford the most expensive system, you should still have a budget. Believe it or not, people without budgets are more vulnerable to scams and fraud than people who set a budget.

Having a budget means you have defined your needs and preferences and possess a sense of direction. Otherwise, you will simply be looking at different options and will most likely pick a mismatch. If you are double-minded about whether upgrading to a new system will help, you should consider the maintenance and repair costs of your existing unit with the new one.

But if you have decided on a new HVAC unit, you will need to contact your contractor and communicate your budget along with your needs and preferences. The contractor will suggest you the best option including or excluding the associated HVAC installation costs.

Create Zones

If you are installing a ductless HVAC system, you will need to create zones. For instance, if you are running a restaurant, you will be needing different zones for the kitchen and the dining area. In some cases, the zones are obvious depending on the layout of the building. These zones are created to tackle the amount of heat produced in different areas.

Planning Installation

Once you have decided on the prerequisites, it is time for installing the new HVAC system. If you have a ducted system, a technician from HVAC repair services Stony Brook will simply attach the new HVAC system with the existing ductwork without affecting your business.

However, if a new ductwork network needs to be installed, you will need to shut down your business for a couple of days or even weeks depending on the job. With zoned ductless systems, you have the liberty to pause operations in some areas without affecting others.

Considering all the factors, the contractor will finally move on and begin installing the new system under your supervision.

Commercial HVAC Installation Mistakes To Avoid

Constantly Running A Commercial HVAC Unit

One of the most common mistakes with HVAC units is constantly running. Although most modern HVAC systems come with programmable thermostats, if your system does not have one, you will need to purchase an aftermarket thermostat.

Constant running of the HVAC system in a building nobody is using will simply raise your energy bills and affect the lifespan of the unit. To avoid expensive repairs down the road, you should set the system to turn off after a certain period of time.

If that is not the case, you should manually turn off the system.

Choosing The Wrong Installation Service

Choosing the right installation service is as important as choosing an HVAC unit of the right size. If the system is not properly installed, it will not put out optimum performance and would be relatively less effective and efficient.

In most cases, business owners tend to spend a huge sum of money on HVAC systems but choose amateurs who perform a shoddy installation job. This is why you need someone professional with technical knowledge and skills.

Installing a commercial HVAC unit is not cheap but the disadvantages of an improper installation job outweigh the benefits in the long run. Eventually, you will find yourself constantly paying for both minor and major repairs that will accumulate into a large sum.


Installing a commercial HVAC system is not that complicated. Following the tips mentioned above, you will surely get the most out of your investment. Make sure that you choose one from reputable commercial HVAC companies Huntington and follow a maintenance schedule to keep things running as smoothly as possible. Commercial HVAC system must be maintained by a professional to never skip the scheduled maintenance of your air conditioning system.
